A recent study of patient violence toward hospital physicians and nurses offers a welcome perspective in its classifying of aggressive behaviors as workplace violence. While patients and families are widely recognized as sources of rude behaviors, we need to shed light on passive aggressive and other low-level rude behaviors that take place frequently amongst hospital personnel as well. Studied under the term "workplace incivility," these seemingly insignificant behaviors that show lack of regard for colleagues have far reaching negative consequences...

PURPOSE: To present a unique case of decompression retinochoroidopathy presenting with intraretinal, subretinal and preretinal hemorrhages. METHODS: A 65-year-old hypertensive female presented with diminution of vision in right eye of 1-week duration. She had been a known case of primary open-angle glaucoma and had undergone trabeculectomy with mitomycin C in right eye 1 week back. Her day 1 postoperative intraocular pressure was 6 mmHg. Her left eye had undergone Ahmed glaucoma valve surgery for the same 2 years back...

INTRODUCTION: Our study compares the biomechanical properties of the cornea in patients with long-term pre-existing (for at least 10 years) systemic sclerosis (SSc) with those of healthy suspects. MATERIAL/METHODS: The examination was performed in 14 systemic SSc patients and 38 healthy volunteers. Non-invasive assessment of corneal biomechanical parameters, including central corneal thickness (CCT), corneal hysteresis (CH) and corneal resistance factor (CRF), was performed in one randomised study eye in accordance with a standardised protocol...

PURPOSE: Sleep apnoea syndrome (SAS) is often associated with glaucoma, and intermittent hypoxia, present in SAS, can contribute to glaucoma pathogenesis. However, the relationships between SAS, high systemic oxidative stress and the speed of glaucoma progression are unclear. Thus, we investigated these relationships in glaucoma patients with and without SAS. METHODS: Peripheral blood samples were collected from 166 eyes of 166 Japanese patients: 42 controls, 109 open-angle glaucoma (OAG) patients without SAS and 15 OAG patients with SAS...

Intraocular pressure (IOP) is the primary risk factor for developing glaucoma, yet little is known about the contribution of genomic background to IOP regulation. The present study leverages an array of systems genetics tools to study genomic factors modulating normal IOP in the mouse. The BXD recombinant inbred (RI) strain set was used to identify genomic loci modulating IOP. We measured the IOP in a total of 506 eyes from 38 different strains. Strain averages were subjected to conventional quantitative trait analysis by means of composite interval mapping...

AIM: To estimate the efficacy and safety of the Ahmed implant in patients with high risk for failure after glaucoma surgery. METHODS: In 342 eyes of 342 patients with refractory glaucoma, even with application of medical treatment, the Ahmed valve was introduced for intraocular pressure (IOP) control, in the period of the last 20y. The nature of glaucoma was neovascular in 162 eyes, pseudophakic or aphakic in 49 eyes, inflammatory in 29 eyes and non working previous antiglaucomatic surgical interventions in 102 eyes...

BACKGROUND/AIMS: There is considerable interest in novel techniques to quantify choroidal blood flow (CBF) in humans. In the present study, we investigated a novel technique to measure CBF based on laser speckle flowgraphy (LSFG) in healthy subjects. METHODS: This study included 31 eyes of 31 healthy, non-smoking subjects aged between 19 and 74 years. A commercial LSFG instrument was used to measure choroidal vessel diameter (CVD) and relative flow volume (RFV) in choroidal vessels that were identified on fundus photos, an approach that was used previously only for retinal vessels...

Laparoscopic surgery is often prolonged and requires positional changes to facilitate surgical access. Previous studies reported intraocular pressure (IOP) changes in one fixed position. This study investigated the effect of desflurane and propofol anesthesia on IOP during repeated positional changes. A total of 46 patients undergoing laparoscopic colorectal surgery were randomized into desflurane or propofol groups. IOP was measured using a handheld tonometer at seven time points: before induction (baseline), after endotracheal intubation, after pneumoperitoneum, after the first Trendelenburg and right tilt position, after reverse Trendelenburg and right tilt position, after the second Trendelenburg and right tilt position and before endotracheal extubation...

Aim. To study the outcome of cataract surgery in eyes with pseudoexfoliation without signs of glaucoma. Methods. This prospective study was done over nine months on patients with pseudoexfoliation undergoing small incision cataract surgery. Only patients with normal intraocular pressure (Central Corneal Thickness Corrected), normal cup disc ratio and open angles were included. Patients on anti-glaucoma medication were excluded. Patients underwent surgery performed by a single senior surgeon. Intraoperative and postoperative day (POD) 1 findings were noted...

Worldwide, and especially in Asia, myopia is a major vision-threatening disorder. From AD 1600 on, to prevent myopia, authors warned against near work without sufficient pauses. There was an abundance of theories about the causes of myopia, the most common one being the necessity of extra convergence on nearby work with thickened extraocular muscles and elevated intraocular pressure. Ocular tenotomies against myopia were in vogue for a while. Axial lengthening of the eye in myopia was mentioned around 1700, but it took 150 years to become accepted as the most prevalent sign of high myopia...

Objective: To observe the change of refractive status and possible influencing factors for patients with different corneal power who underwent small incision lenticule extraction (SMILE) surgery. Methods: Prospective cohort study was performed for patients who underwent small incision lenticule extraction (SMILE) surgery at Daping Hospital and Research Institute of Surgery of Third Military Medical University between January and August 2016. The patients were divided into 3 groups according to their corneal power: low curvature group (K(1)≤41...

PURPOSE: To determine the accuracy of a Bayesian learning scheme (Bayes') applied to the prediction of clinical decisions made by specialist optometrists in relation to the referral refinement of chronic open angle glaucoma. METHODS: This cross-sectional observational study involved collection of data from the worst affected or right eyes of a consecutive sample of cases (n = 1,006) referred into the West Kent Clinical Commissioning Group Community Ophthalmology Team (COT) by high street optometrists...

Humans across the globe shows a remarkable diversity in colouration of skin, hair and eyes (Jablonski & Chaplin, 2017) reflecting adaption of pigmentation genes within populations to their environment (Sturm & Duffy, 2012), as well as other evolutionary forces. Skin colour is highly correlated with incident levels of solar UV, and this has led to hypotheses that the need for vitamin D synthesis and protection from photolysis of folate are major balancing selective pressures modulating melanogenesis in the epidermis necessary for both healthy bones at high Northern latitudes experiencing low solar irradiance, but also shielding the skin from the high equatorial sun exposure...

Optimum levels of attentional control are essential to prevent athletes from experiencing performance breakdowns under pressure. The current study explored whether training attentional control using the adaptive dual n-back paradigm, designed to directly target processing efficiency of the main executive functions of working memory (WM), would result in transferrable effects on sports performance outcomes. A total of 30 tennis players were allocated to an adaptive WM training or active control group and underwent 10 days of training...

OBJECTIVE: This study aimed to determine whether children's headache drawings can distinguish between pseudotumor cerebri and migraine. BACKGROUND: Headache features associated with pseudotumor cerebri (pseudotumor; idiopathic intracranial hypertension) are nonspecific and are difficult to distinguish clinically from migraines. Children's headache drawings have a high predictive value for migraine versus nonmigraine headaches. We hypothesized that drawings could help to differentiate pediatric headaches due to pseudotumor cerebri from those associated with migraines...

The utility of Goldmann applanation tonometry (GAT) for monitoring intraocular pressure (IOP) in open-angle glaucoma (OAG) patients with a history of laser refractive surgery was investigated by comparing IOP fluctuations measured using GAT and dynamic contour tonometry (DCT) on the same day. In this retrospective study, patients were divided into one of two subgroups according to IOP fluctuation values using GAT: 43 eyes in the low IOP fluctuation group (LIFG [GAT fluctuation ≤1.7 mmHg]); and 55 eyes in the high IOP fluctuation group (HIFG [GAT fluctuation >1...
